MOUNTING Application vfilled. September The invention is in earth working implef ments of the class in which frame connect-v ed concavo-conv'ex Vdisks are employed for operating upon the soil,` and relates particularly to the means of supporting the soil working` disks from the framex It is well understood with, respect to implements of this class, that when the disks are positioned with their axes aligned transversely relative to the line of advance, the disks are ineffective as soil cutters and with the disks so positioned the implement may be transported without any consider-`v able action on the soil.

lt is likewise well understood that an effective soil cutting action is obtained ,from such implements by positioning the disks with their axes at an anglel tothe line of advance, and furthermore that when the' disksare 4so positioned, by tiltingthe disksA so their axes are inclined to the'horizontal, the disks will effectively operate on inclined surfaces, such as the downwardly and inwardly converging faces of trenches or the downwardly and outwardly diverging faces of ridges, land'that under any of these various conditions the soil may be either thrown outwardly or inwardly, depending upon whetherl the disks are positioned with their concave faces toward the sides or toward the center of the implement.

It is .common practice in some sections of the country to ridge the fields where row crops are to be planted. In some instances the seed is planted on theridges, in other instances in the bottom of the trenches depending upon the characteristics of the plant, the condition of the soil, Vand the season. It is therefore desirable that the implement used for cultivating such fields be adapted for working either the downwardly diverging sides of the ridges or the downwardly converging sides of the trenches.

The implements heretoforel devised for work of this character, with which I am familiar, have had the disks mounted in gangs and have been provided with means for moving the axes Vof the disks relative to the frame to carry the disks into and out of cutting angle, and have also been provided with means for -inclining the axes of the disks relative to the` frame and to the horizontal to position the disks for trench i or ridge work, but this latter position for or gang supports laterally with respect to the implement frame and was in the nature 1,641,688 sereni erstes.

of a iii-:ed adjustment, therefore the disks I were still inclined with respect to the frame and tothe horizontal after the axes of the disks were moved out of .cutting angle and into transverse alignment; consequently when turning the implement on the head-y land at the ends of trenches or ridges or when moving it from field to field `while adjusted for suchy work, the weight of the entire implement was sustained by the inner disks of each gang, ory the outer disk of each gang, depending upon the particular adjustment of the gangs. The, excessive weight thus imposed on the two supporting` disks forced them to cut into and tear` the'soil, which was often objectionable. At such times these implements were unstable and were disposed to rock laterally, particularly when supported on the two innermost disks, and furthermore the` disk gang bear. ings and boxes were subjected to severe and improper strains. l 'f f In contrast with these earlier implements, the disks ofthe improved implement herein described are supported from the vframe in such a manner that when they are adjusted for trench or ridge work and they are moved intoV and outof cutting angle, such movement of the disks will simultaneously and automatically, respectively incline'and straighten their axes withrespect-to horizontal planes.

It is an object of the invention to provide improved means for supporting the disks from the frame.

AvIt is also an object of the invention to provide means for supporting the disks from the frame that can be adjusted so that the shifting of the disks into and out of cutting angle will simultaneously tilt the disks into and out of inclined position relative tothe horizontal. i

It is a further object of the invention to provide for adjusting the disk supports to' regulate the inclination relativepto the horizontal that the disks assume when moved into cutting angle. j l

Other objectsand advantages of the invention are fully disclosed in the following` specification anu drawings.

vfiteferring to the drawings which illus# and in which like numerals designate corre sponding parts.

Fig. l is a side elevation of a machine embodying the invention, the earth Working disks being shown in transverse alignment.

Fig. 2 is a top plan view of the machine as shown in Fig. l. Fig. 3 1s a fragmentarv side elevation .showing the supporting means that connect `the earth Working disks with the frame ad )usted to an inclined position, the disks be-y ing in transverse alignment.

Fig 4 is a fragmentary side elevation,A the concave side of the disks facing the center', and the disks positionedto Work on the side of aridge. n

Fig. 5 is a view similar to Fig. 4 but With the disks positioned to work on `the side of a trench.

Fig. 6 is a fragmentary side elevation but with the convex side of the disks facing the center, the disks positioned to Work on the ,the frame, and are connected With the forwardly projecting ends of a U-shaped center frame member 1]., which are connected by suitable spacing brackets 12-12j the closed end of the'member 1l being secured to the bar lOat the middle of the rear side o-f the frame, the Whole forming a substantial con-r neetion and support for the vearth Working devices. f y

Then draft animals are used to drawn7 the implement a pole 13 is secured to the forwardly extending portion of the frame formed by the bars l0.-ll and the spacing brackets 12, and a draft 4bar 14 .is mounted on a coupling pin 15 carried by a .draft bracket formed by the straps 16e-17 which aua secured `to fthe forwardly extending poreA tion of the frame.

If it is desired to draw the implement with a tractor, the pole and draft bar can be removed and the draw bar of the tractor can be hitched to the coupling pin 14.

Spacing brackets l8-.-l8 `are secured between vthe rear portions of .the centre frame member and support seat .bars 19-.19 upon l which is mounted the operators sea-tl2t).

A bracket 2l for supportingv the tool carrier is securely `clamped by clip bolts 22 to kthe frame bar l() at each side of the middle of the frame, but the brackets can be .shifted along the frame bar to properly space the earth working tools relative to the plant rom7 by loosening thebolts 22. Each bracket 2lv is formed With a horizontal bearing portion 23 in which is supported a pin 24 upon Which is pivotally mounted the ears 25j-25 of a yoke like member 26 having asleeve portion 27.

Extending preferably from the sleeve portion 27 of each yoke is a socket Vlike lug 28 to which is secured alever 29, the latter carrying the usual plunger lock rod 30 adapted to engage the notches 3l of alever rack 32 that is carried by the bracket 21. The usual spring 33 is mounted on the lever to cause the plunger rod to engage the notches of the rack and the lever is also provided With the customary handle 34 to lift'tlie plunger rod against the tension of the spring 33, to release vthe lever from its rack.

VPivotally mounted in each sleeve 27 is a tool carrier, comprising` a stem B5 to vvthe lower end of which is' rigidly secured a transverse bar 36, the latter having an opening 37 therethrough near each end. The stem is held in place in its sleeve by a spring Cotter' 38 extending through the stem above the sleeve. Y

Securely attached to the under side of each bar 36 is a downwardly project-ing bracket 39 in the form of an inverted U. best seen in Fig. 8, and to the lower end of each arm of the vbracket is bolted a half box 40 that receives the disk bearing, the other half -boX for the bearing being indicated by the numeral'4l, the two halves of the box being held together by bolts 42. The soill Working tools, in this instance a pluralityl of disks, are arranged in the form of a gang in the usual manner wherein the disks 43 are mounted on a headed square shaft 44 and are 'held in spaced relation by bearing gang for cleaning the disks when desired.

The scraper blades 47 are secured in spaced relation to a longitudinally movable bar 48 which is supported by .arms 49- 49` that eritend forwardly and are securely bolted to bracket 39. A spring 50 mounted on the bar 48 between one of thevarms 4.9 and suitable abutment carried by the barj such as one of the scraper blades, acts to press the bar endwise and hold the scraper blades against the concave faces of the disks.

TWhen it is desired to shift the scraper blades` away from the disks, a. cam lever 5l. pivotall-y mounted on vthe bar 48 near one of the arms 49r can be turned, the end'of the lever engages the -arm 497 and moves the bar 48 endivise against the pressure of the spring 50 carrying the Scrapers out of enga-gement With the disks. 'Y i `Each side of the frame supports'a rock ian A lever 54 secured to each rock shaftcarries the usual plunger lock rod '55 adapted to engagethe notches 56 ofa lever rack 57 thatis secured' to the frame bar 11. The usual spring S is mountedfon the lever to cause the plunger rod to engagethe notches of therack, and the lever is also provided with the customary handle 59 to lift theV plunger rod againstl the tension of 4the spring 58 to release the lever from its rack.

An arm 60 isclamped by a. clip bolt 61 to each ofthe rock shafts so as to be ad'- justable'longitudinally thereof, and 'at'its lower end the arm 60 is pivotally connected by pin 62 to one or the other of holes 63--64 provided in the forward end ofa link 65, the rear portion of which is formed into a hooklike attachment 66 adapted' to engage the hole 37 in the end of the transverse bar 36 of the gang unit that is .toward the center of the machine.

From 'the vforegoing description it will be understood that bymeans of the levers 29, the yoke members 26 and disk carriers with the disk gang units carriedthereby can be rocked about the horizontally disposed pivot pins 24 o f the frameV brackets 21, and` that with the levers 54 and'their link connections 65 to the transverse bars 36 of the disk carriers. the latter together with their Y stems and the disk gangs lcan be swiveled l v l aXes of the disks, simultaneously with their relative to the sleeves 27.

, If the implement is to be usedV on a field i the surface of which is smootlntheoperator will adjust the levers 29 so the sleeves 27 are in vertical position as shown in F ig. 1, and assuming it is desired to throw the soil away from thercenter or plant'row,-'the disk gangs are turned yin the sleeves 27 so the concave faces of the disk are toward the sides as shownlin Figs. 1 and 2.` The arms are connected to the front holes 63 in the forwardvends of the links 65, the rear ends of the links are attached to the inner ends of the transversebars 36, so that when the levers 54 are shifted forwardly, the inner ends of the gangs will be moved back, the gang stems 35 swiveling in the sleeves 27, thereby shifting the axes of the disks relative to transverse vertical planes-and carrying the disks intocuttingy angle in a manner that is common with the 'ordinary disk harrow. vTo move the disksu into non-cu!l ring position the operator shifts the'lever-54 to its rearward position-as shown-in Fig. 1 which` brings the aXes of the disks into transverse alignment. I i y Assuming however that the field has been ridged and that the plants to be cultivated are in -thebottom of the. trenches formedl by soil laway fromthe center' or plant rows, the levers 29 are shifted rearwardly,v thereby tilting the yokes 26 and sleeves y27 to van'ind clination relative to they vertical as shown in Fig. 3. If'the ylevers 54`be now shifted forwardly, the inner ends of the gangs will be movedl back carrying the disks into c ut-v ting angle, the gang stems 35 swiveling in the sleeves 27 but owing to the swivel aXes now being inclined, due to thel tilting ofthe upper ends of the sleeves 27 and stems 35 rearwardly, the aXes of the disks will swing to an inclined position relative to horizontal planes simultaneously with their movement out of transverse vertical planes, and V they will assume the position shown in Fig. 6 wherein the axes of the disks converge downwardly and rearwardly. VTo move the disks into non-cutting position, and 'withv` their axes transversely aligned,v the operator simply shifts the levers 54 back totheir rearward position as shown in Figs. 1 and 3. 'If the plants to be cultivated are onfthe 29 are shifted forwardly to tilt the yokes 26 and the sleeves 27 to a4 forwardinclination relative to the vertical. If thev levers 54 be now shifted forwardly the innerv ends of` the gangs will vhe moved backcarrying the disks into cutting angle, the gang stems 35 swiveling in the sleeves 27, but-*owing'to 'the directionv of inclination of the sleeves 27 and stems 85", comprising t-he swivel axes,

'lull `being opposite to that shown in Fig. 6,thc

movement outof transverse vertical planes,

'will swing to an inclined position relative to the horizontal, *oppositev to that shown in Fig. 6, and they will assume'the position shown in Fig. 7 wherein thev axes of the disks convergev upwardly and rearwardly.. To transversely align the disks and` make them non-effective'as cuttersthe operator simply shifts the levers 54 vback intoy their rearward position. f I

If the implement is to vbe used on a field thesurface ofwhich is smooth and it is desired to throw the soil towardthe center or plant row, thev operator will adjust the levers 29 so the-sleeves 27y are vertical as seen in Fig. 1, the links aredetached from the transverse bars 36 and the disk gangs are turned end forend by rotating' thev stems 35 in the sleeves 27 so that the concave-faces ofthe disks are toward the center,` the links 65 are attached'to Vtheholes 37 in theends of the transverse'bars 'now toward the center, the levers 54 are shifted to their forward position on the-racks 57, the rock shaft arms -60 are'connected with the holes 64`in the forward ends ofl the links 65, whereupon by shiftin the levers 54 rearwardly the inner ends o the gangs will be drawn forwardly,

io .vers 29 lare shifted rearwardly thereby tilting'the yokes 26 and sleeves 27 to an inclination relative to the vertical as shown in Fig. 4.' If the levers 54 be now 'shifted rearwardly the inner ends of the gang will be moved forward, carrying the .disks into cutting angle7 and owing to the `swivel Vaxes formed by sleeves 27 andstems '35 being inclined, the axes of the disks will swing to an inclination relative to the horizontal si- 2i multaneously with their i'novenie'nt-into cuttingfangle, andthe disk gangs, will assume the position shownr inr Fig. 4 wherein the axes of the disks converge upwardly and forwardly. vTol-return the disks from this `position to *non-cutting position with their axes transversely aligneda itis `only necesi saryto shift-the levers ito their forward position. l Y v s rIf, thev side walls of the trenches are to be disked and it is `desired to throw thelsoil towardthe center, or toward the plants, in `the event `theseedl-has been placed in the trenches, the levers 29e/ire shifted forwardly to tilt the yokes 26 and thesleeves 27 toa forward inclination relative tothe vertical.

[If the levers 54 rbe now shifted rearwardly Fthe inner end-s of the gangs will be moved inclination ofthe sleeves 2'( and stems `35,V

comprising the swivel axes, being lopposite to that shown in Fig. 4,the axes of the disks,y simultaneously with `their ,movement out oftransverse vertical planes, will swing yto an inclination Arelative to the horizontal Vopposite to that shown in Fig. and will assumethe position as seen in Fig, 5 wherein the axis vof ,the disks converge downwardly and forwardly. 'To restore the'galngsl VtoV non-cutting position in which the axes of the disks are in alignment both with respect to transverse vertical planes and horizontal planes,-the levers 54 are shiftedfto their forward position on the racks 57. f

It will* be understood' that under any conditions of adjustment of they gangs de- `,scribed,vthe operator can govern thefamount ofl cutting angle given the disks,y or Y the extent to which the Aaxes, of the Vgangs will be inclined, relative `to thehorizontal, by the distance the levers *54;29, respectively,A are moved along their racks, andthaftby the yproper adjustmentA of the vt-wo sets of levers anyrdesired combination ofthe two angles meines may berobtained; furthermore the rgang .at either-side is adjustable independently4 of the other and regardless of how much o i-Aliow little the levers 29 are shifted to tilt the Y sleeves 27 and stems 35,Y away from the vertical, either forward or rearward, when a gang is. moved into cutting angle with its lever 54: it is simultaneously and automatically inclined relative tothehorizonta-l, and when a gang is movedfrom cutting angle to nonn cutting position, in which its axis is `aligned with respect to transverse vertical planes, the axis of the gang is likewise simultaneously and automatically aligned with respect to horizontal planes.- l

Itl will be understood that when the supporting brackets 2l are shifted along the .frame barlO tovary the Spacing between the gangs of disks, the arms G0 are likewise shifted along the rockv shafts 52 to maintain the proper. relationship between the levers fandthe gan-gs; also. that when the gangs are reversed end for end,' so the conc-ave faces of the disks are `toward the center instead of rtoward vthe sides,v or vice versa, the scraper supporting arms 49 are unbolted from the brackets 39 and thescraper units transposed from one gang to the otherand .iebolted in place. v 7 Y Y V-hile I have used the term gang in con- `nectionl with the 4description ofthe sets lot .disks7 l do not wish to limit mysclfvin all cases to yafplurality-of disks in each set or fto'afplnralitv ofsets., :for therel are instances where' it is advantageous toy mount a tdisk :in vthe-manner described;

So far as l am k.f1-ware lain the virst in the art Ito provide a support for adisk gane that vwill .automatically .incline the disks relative .to the horizontal by the movement of the disks into cutting angle, and that'will automatically straighten the disks relative to the horizontal by the movement ofthe disks from cut-ting angleto non-.cutting position. `My invention is therefore generic in character and the claims are to 'be construed accordingly. lVhile-it is possible that -vari vations may .be-made inv thestructure illus- .tr-ated and herein particularly vdescribed it is mv intention that all such possible modi-- cations as are within the spirit of my invention shall be covered by the following claims.
